|Official Title:||Phase 2 Study of Pralatrexate in Female Patients With Previously-treated Advanced or Metastatic Breast Cancer|
- Objective Response Rate (ORR) [ Time Frame: Assessed at the end of each even-numbered cycle (every 8 weeks), or per standard of care but no less than 4 weeks and nor more than every 12 weeks (+/- 1 week) if treatment has ended. ]Tumor response evaluation was performed using RECIST 1.0 using CT/MRI. Proportion of patients achieving a CR or PR is considered in the overall response.
- Duration of Response (DOR) [ Time Frame: Assessed at the end of each even-numbered cycle (every 8 weeks), or per standard of care but no less than 4 weeks and nor more than every 12 weeks (+/- 1 week) if treatment has ended. ]One patient has a PR as response and duration of response was provided for that patient.
- Overall Survival (OS) [ Time Frame: Assessed at the end of each even-numbered cycle (every 8 weeks), or per standard of care but at least every 4 weeks and no more than every 12 weeks (+/- 1 week) if treatment has ended. OS will be collected for up to 2 years from start of pralatrexate. ]Number of days from first dose of pralatrexate to death.
- Incidence of Adverse Events (AEs) and Laboratory Abnormalities [ Time Frame: Recorded at all study visits: every 2 weeks while on treatment and at safety follow-up (35 +/- 5 days post-last dose) or early termination visit (at time of withdrawal). ]
